Hi Everyone,
Thanks for all your input. After a much consideration and after reading all your ladies comment, I think I am going for 4 weeks. It will give them at least 2 weeks to look for someone and 2 weeks to hopefully train the person.
But, I am also preparing for the worst as well. If they decided to let me go earlier, then we just have to start the move a little earlier than expected. At least I know I did my part ( at the best intention) by giving them 4 wks.
I really appreciate everyone's comment, thanks !!
